If you’re a fan of Bighorn Arms actions you’ll be an even bigger fan of the PROOF Research pre-fit carbon fiber barrel designed for the Bighorn Arms Origin action.
Our pre-fit Origin carbon fiber barrels are threaded and chambered and are easy to install. These are shouldered barrels that come pre-headspaced and do not require gauges. Just spin them on, torque, and go shoot. Our drop-in barrels for Bighorn Origin actions are available in carbon fiber in a variety of lengths and twist rates.
Up to 64% lighter than traditional steel barrels of similar contour.
Improved heat dissipation for cooler and longer lasting barrels.
Wrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin.
